The radius of a circle is 8 in. Find its area in terms of \piπ.
Answer:
201.06 in
Step-by-step explanation:
I'm guessing you meant πr² because that's what you use to find the area of a circle.
Anyways, we know what the radius is, it's 8, so now we just need to plug it in.
π8² = 201.06
or you can do
3.14(8²) = 200.96
Using π just makes it more exact.
Answer:
201.1 in (approx.)
Explanation:
ok x so first I will multiply 8^2 by pi, that gives me an infinite decimal.. but after rounding it up to 1d.p, we get 201.1 inches which is your answer

help plz , i don't know how to find it
Answer:
y = 2x + 4
Step-by-step explanation:
y = mx+b
m represents the slope, and b is the y-intercept
The slope is 2 as it's going up 2 unit squares each time, and the b is 4 because that's where the y-axis gets intercepted.
so the answer is y = 2x + 4

In a two-digit number, the units digit is six less than three times the tens digit. Four times the units digit minus five times the tens digit equals 11. Find the digits.
Answer:
The tens digit = 5
The units digit = 9
The two digit number is 59
Step-by-step explanation:
Let the tens digit be represented by x
The units digits be represented by y
In a two-digit number, the units digit is six less than three times the tens digit.
y = 3(x) - 6
y = 3x - 6
Four times the units digit minus five times the tens digit equals 11.
4(y) - 5(x) = 11
4y - 5x = 11
We substitute
4(3x - 6) - 5x = 11
12x - 24 - 5x = 11
Collect like terms
12x - 5x = 11 + 24
7x = 35
x = 35/7
x = 5
y = 3x - 6
y = 3(5) - 6
y = 15 - 6
y = 9
Hence,
The tens digit = 5
The units digit = 9
The two digit number is 59
Answer:
5=tens 9=units

Answer: 32w
Step-by-step explanation:
Write the point-slope form of the given line that passes through the points (0, 3) and (4,0). Identify (x, y) as the X-
Intercept of the line. Include your work in your final answer. Type your answer in the box provided to submit your
solution.
Answer:
y-3= -3/4 -(x+0)
Step-by-step explanation:
y2-y1 3-0= 3
x2-x1 0-4= -4
slope is - 3/4
y= mx=b
y = -3/4x + 3

use the multiplier method to increase £258 by 43
Answer:
The new value after an increase
of £258 by 43 will be: 368.94
Step-by-step explanation:
As we have to increase £258 by 43 using the multiplier method.
Let 'n' represent the new value after the increase of £258 by 43 using the multiplier method.
Using the formula
n = 258 + percentage increase
[tex]=258+\left(43\%\:258\right)[/tex]
[tex]=258\:+\:43\%\:\times 258[/tex]
Factoring out 258
[tex]=\left(1\:+\:43\%\right)\:\times \:258[/tex]
as 1 = 100 / 100 = 100%
so
[tex]=\left(100\%\:+\:43\%\right)\:\times \:258[/tex]
[tex]=143\%\:\times \:258[/tex]
[tex]=\frac{143}{100}\times 258[/tex]
[tex]=\:\frac{143\times 258\:\:}{100}[/tex]
[tex]=\:\frac{36,894\:\:}{100}[/tex]
[tex]=368.94[/tex]
Therefore, the new value after an increase
of £258 by 43 will be: 368.94

Two trains leave Raleigh at the same time one traveling north and the other south the first train travels at 50 miles per hour and the second at 60 miles per hour in how many hours will the trains be in 275 miles apart
Answer:
2.5 hoursStep-by-step explanation:
Step one:
given data
for train one
speed= 50miles per hour
for train two
speed= 60miles per hour
the total distance between both trains=275miles
Step two:
the expression for speed= distance/time
so that, distance= speed*time
let the time be t
we are going to combine both distances
train one distance =50t
train two distance =60t
Hence total distance
50t+60t=275
110t=1=275
t=275/110
t=2.5 hours
It will take 2.5 hours

Does the table show a proportional relationship? If so, what is the value of y when x is 11
Answer:
Yes, the table shows a proportional relationship
The value of y when x is 11 is 1331
Step-by-step explanation:
Let us check the relation between x and y in the table
∵ x = 4 and y = 64
∵ 64 = 4³
∴ y = x³
∵ x = 5 and y = 125
∵ 125 = 5³
∴ y = x³
∵ x = 6 and y = 216
∵ 216 = 6³
∴ y = x³
∵ x = 10 and y = 1000
∵ 1000 = 10³
∴ y = x³
∵ All the values on the table give the same relation
∴ x and y are proportion
∴ The table shows a proportional relationship
∵ y = x³
∵ x = 11
∴ y = (11)³
∴ y = 1331
∴ The value of y when x is 11 is 1331
